For this material, there is no stocks for both hot rolled bar and hot forged bar, because China domestic used it very rarely, so no stockiest will stock them. If we want to order 36NiCrMo16 material, usually the MOQ is 10tons.
6：Forging processing
Put the 36NiCrMo16 ingot into the furnace and heat to 1150-1200℃
Forge the ingot, forging temperature should be not less than 850-900℃
Cooling in the air or in the furnace after forged
7: Heat treatment
Soft annealed:
Heat 36NiCrMo16 steel to 650-700℃ in the furnace
Soak at this temperature in the furnace
Cooling in the furnace
Normalized:
Heat 36NiCrMo16 steel to 880-950℃ in the furnace
Soak at this temperature in the furnace
Cooling in the air
Quenching and tempering:
Heat 36NiCrMo16 steel to 865-885℃ in the furnace
Soak at this temperature in the furnace
Quench in water, oil or air
Temper steel at 550-650℃ in the furnace
Take out of 36NiCrMo16 steel from furnace and cool in the air.
Remark: The conditions given above are for guidance, at the temperatures at the lower end of the range are generally applicable to hardening in water and those at the upper end for hardening in oil.
8: Weldability
36NiCrMo16 steel has relatively poor weldability. For steel materials, weldability is strongly related to the carbon content. When the carbon content exceeds 0.25%, weldability begins to deteriorate. The carbon content of 36NiCrMo16 is approximately 0.36%, so its weldability is not ideal. Additionally, the high nickel and chromium content in this alloy steel can further increase the risk of cracking during welding.
9：Application
36NiCrMo16 is a high-strength, high-toughness alloy structural steel, which is widely used in key components requiring high mechanical properties and fatigue strength. Its main application areas include:
1): Used in the manufacture of aircraft landing gear, engine drive shafts, turbine components and other key load-bearing parts.
2): Used in the manufacture of high performance engine crankshafts, connecting rods, transmission gears and other key moving parts.
3): Used in the manufacture of crankshafts for large diesel engines, gas turbine shafts, gears and bearing parts for mining machinery.
4): Suitable for manufacturing high load gears, bearings, precision shaft parts, etc.
